WS203 - Motion and TH Comfort Sensor with Energy Saving

The Milesight WS203 is an environmental monitoring device that
combines motion and temperature/humidity (TH) sensors. By detecting motion within an 8-meter range based on PIR (passive infrared) technology, the WS203 can trigger TH detection and periodically report environmental status via the LoRaWAN® network. With easy configuration and wireless detection, the WS203 offers a reliable and convenient solution for space and TH optimization. Compatible with the Milesight LoRaWAN® gateway and the IoTCloud platform, it enables real-time monitoring of occupant status for effective remote management. The WS203 can be applied in various contexts, including smart offices, buildings, hospitals, and more.
